Description
Die vorliegende Erfindung betrifft drahtlose Kommunikationssysteme. Insbesondere betrifft die vorliegende Erfindung ein System zur Unterstützung eines fortentwickelten terrestrischen Funkzugangsnetzes (E-UTRAN) eines universellen mobilen Telekommunikationssystems (UMTS).The The present invention relates to wireless communication systems. In particular, the present invention relates to a system for supporting a advanced terrestrial radio access network (E-UTRAN) of a Universal Mobile Telecommunication System (UMTS).
Verschiedene Arten von drahtlosen Zugangssystemen wurden entwickelt, um verschiedene Arten von Diensten und Fähigkeiten bereitzustellen. Einige Beispiele für drahtlose Zugangssysteme umfassen drahtlose lokale Netzwerke (WLANs) (wie etwa IEEE 802-basierte Netzwerke) und zellulare Netzwerke (wie etwa das terrestrische UMTS-Funkzugangsnetz (UTRAN), das Funkzugangsnetz (GERAN) eines globalen Systems zur Mobilkommunikation (GSM)/der verbesserten Datenrate für die GSM-Evolution (EDGE) oder ähnliche). Jedes dieser Netzwerke wurde entwickelt und maßgeschneidert, um spezifische Anwendungen bereitzustellen.Various Types of wireless access systems have been designed to be different Types of services and skills provide. Some examples of wireless access systems include wireless local area networks (WLANs) (such as IEEE 802-based Networks) and cellular networks (such as the terrestrial UMTS radio access network (UTRAN), the radio access network (GERAN) of a global system for mobile communications (GSM) / the improved data rate for GSM evolution (EDGE) or similar). Each of these networks has been developed and tailor made to be specific To provide applications.
Vorschläge für ein E-UTRAN
(langfristige Evolution für
UTRAN und fortentwickelten Node B (E-Node B)) wurden gemacht, um
die drahtlose Systemkapazität
zu verbessern und die Leistung zu erhöhen. Das E-UTRAN wird erhebliche
Vorteile gegenüber
vorhandenen drahtlosen Kommunikationssystemen bereitstellen, und
durch die von dem E-UTRAN bereitgestellte höhere Bitrate und die geringere
Latenz können
zusätzliche
Dienste verfügbar
sein.
Gegenwärtig sind drahtlose Sende/Empfangseinheiten (WTRUs) mit mehreren Betriebsarten, die konfiguriert sind, um mehrere drahtlose Kommunikationssysteme zu unterstützen, verfügbar. Die Fähigkeiten jeder der WTRUs können verschieden sein. Zum Beispiel können manche WTRUs nur UMTS unterstützen, während andere WTRUs mehrere Betriebsarten, wie etwa I-WLAN, GERAN und/oder E-UTRAN unterstützen können. Die WTRUs, die fähig sind, E-UTRANs zu unterstützen, werden auch in Zukunft verfügbar sein.Present are wireless transceiver units (WTRUs) with multiple modes of operation, which are configured to support multiple wireless communication systems to support, available. The abilities any of the WTRUs can to be different. For example, you can some WTRUs only support UMTS, while other WTRUs have multiple modes, such as I-WLAN, GERAN, and / or Support E-UTRAN can. The WTRUs that capable are to support E-UTRANs, will be available in the future be.
Daher wäre es wünschenswert, ein Verfahren und ein System zur Verfügung zu stellen, um ein E-UTRAN zu unterstützen, so daß die WTRUs derartige zusätzliche E-UTRAN-Fähigkeiten und Dienste empfangen und nutzen können.Therefore would it be desirable, to provide a method and system to an E-UTRAN to support, So that the WTRUs such additional E-UTRAN capabilities and receive and use services.
Die vorliegende Erfindung betrifft ein System zur Unterstützung eines E-UTRAN. Die vorliegende Erfindung erweitert herkömmliche Verfahren und Abläufe zur Unterstützung von mehreren Betriebsarten innerhalb von UMTS-basierten drahtlosen Kommunikationssystemen (d.h. UTRAN), um das Hinzufügen der neuen Technologie (d.h. E-UTRAN) zu dem System zu unterstützen. Die herkömmlichen Verfahren sind in den Standards des Partnerschaftsprojekts der dritten Generation (3GPP) (z.B. TS25.331) spezifiziert. Das System umfaßt hier eine WTRU, ein UTRAN und ein E-UTRAN. Ein herkömmliches UTRAN sendet eine Liste verfügbarer Funkzugangstechnologien (RATs) in einem Abdeckungsbereich des UTRAN an die WTRU. Die Liste umfaßt Informationen, die vorhandene RAT-Attribute betreffen, wie etwa einen Technologietyp, die Bitrate, die Bandbreite oder ähnliches. Die vorliegende Erfindung führt die Informationen in diese Liste ein, die das E-UTRAN betreffen. Die WTRU empfängt diese Liste während des ersten Zugriffs oder während Gesprächsumschaltungsverfahren. Nach dem Empfang der Liste kann eine E-UTRAN-fähige WTRU die WTRU basierend auf der Liste derart konfigurieren/umkonfigurieren, daß sie E-UTRAN-Dienste durch Gesprächsumschaltungsverfahren oder Systemneuauswahlverfahren empfängt. Die E-UTRAN-fähige WTRU kann ihre Mehrbetriebsart/Mehrfach-RAT-Fähigkeiteninformationen, einschließlich der E-UTRAN-Fähigkeit, während des Erstzugangs (d.h. den Anschlußverfahren) oder, wenn sie von einem System angefordert wird, an das UTRAN senden. Während eines normalen Gesprächsumschaltungsverfahrens sendet das UTRAN eine Meßfähigkeitennachricht an die WTRU. Die Meßfähigkeitennachricht umfaßt Parameter, die notwendig sind, um auf einem E-UTRAN-Kanal Messungen durchzuführen. Die WTRU führt basierend auf der Meßfähigkeitennachricht Messungen durch und meldet Meßergebnisse an das UTRAN. Das UTRAN kann basierend auf den Meßergebnissen eine Gesprächsumschaltung zu dem E-UTRAN einleiten. Im Leerlaufbetrieb kann die WTRU basierend auf den früher von dem UTRAN empfangen Fähigkeitsinformationen entscheiden, das E-UTRAN neu auszuwählen. Die WTRU verwendet diese Informationen, um die Sender- und Empfängerbandbreite, die Bitrate, das Frequenzband oder ähnliches zu konfigurieren.The present invention relates to a system for supporting an E-UTRAN. The present invention extends conventional methods and procedures to support multiple modes within UMTS-based wireless communication systems (ie, UTRAN) to assist in adding the new technology (ie, E-UTRAN) to the system. The conventional methods are specified in the standards of the Third Generation Partnership Project (3GPP) (eg TS25.331). The system here includes a WTRU, a UTRAN and an E-UTRAN. A conventional UTRAN sends a list of available radio access technologies (RATs) in a coverage area of the UTRAN to the WTRU. The list includes information pertaining to existing RAT attributes, such as a type of technology, bit rate, bandwidth, or the like. The present invention introduces the information pertaining to the E-UTRAN to this list. The WTRU receives this list during the first access or during call handover procedures. After receiving the list, an E-UTRAN-enabled WTRU may configure / reconfigure the WTRU based on the list to receive E-UTRAN services by handover or system re-selection techniques. The E-UTRAN-enabled WTRU may send its multi-mode / multi-RAT capability information, including E-UTRAN capability, during initial access (ie, the connection procedure) or, if requested by a system, to the UTRAN. During a normal handoff procedure, the UTRAN sends a capability message to the WTRU. The measurement capability message includes parameters necessary to perform measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN can initiate a call transfer to the E-UTRAN based on the measurement results. In idle mode, the WTRU based decide on the capability information previously received from the UTRAN to reselect the E-UTRAN. The WTRU uses this information to configure the transmitter and receiver bandwidth, bit rate, frequency band, or the like.

Die OFDM-HF-Fähggkeit und die OFDM-Meßfähgikeit zeigen dem UTRAN OFDM-HF- und Meßfähigkeiten der WTRU an. Ein OFDM-Kanal kann abhängig von der Systemkonfiguration eine verschiedene Bandbreite und die mit gewissen Diensten verbundene gewünschte Bitrate und Verzögerung haben. Um zum Beispiel die höchste zulässige Bandbreite (z.B. 100 MBit/s) zu erreichen, muß das E-UTRAN unter Verwendung der höchsten zulässigen Bandbreite (z.B. 20 MHz) senden und empfangen.The OFDM RF Fähggkeit and the OFDM measurement capability indicate to the UTRAN OFDM RF and measurement capabilities of the WTRU. One OFDM channel may be dependent from the system configuration a different bandwidth and the have desired bit rate and delay associated with certain services. For example, the highest allowed Bandwidth (e.g., 100 Mbit / s), the E-UTRAN must be highest permissible Send and receive bandwidth (e.g., 20 MHz).
Das E-UTRAN kann mehrere Kombinationen dieser Dienste (verschiedene Bandbreiten für verschiedene WTRUs) betreiben. Daher sollte die Gesprächsumschaltung zu dem E-UTRAN basierend auf den OFDM-HF-Fähigkeiten der WTRU ausgelöst werden. Während der Gesprächsumschaltung, wenn die WTRU Messungen durchführt, wird die WTRU vorzugsweise auf eine gewisse Kanalfrequenz und eine spezifische Bandbreite für die Messungen abgestimmt und konfiguriert. Wenn die WTRU die Messungen an das UTRAN meldet, korreliert das UTRAN die Messungen mit den physikalischen Attributen der E-UTRAN-Kanäle. Dies stellt sicher, daß die Gesprächsumschaltung exakt durchgeführt wird, um den Ziel-E-UTRAN-Kanal zu korrigieren, der die gewünschten Bitraten- und Verzögerungsanforderungen unterstützt.The E-UTRAN can handle multiple combinations of these services (different Bandwidths for different WTRUs) operate. Therefore, the call transfer should to the E-UTRAN based on the OFDM RF capabilities of the WTRU. While the call switching, when the WTRU performs measurements, For example, the WTRU is preferably tuned to a certain channel frequency and a specific bandwidth for the measurements are tuned and configured. When the WTRU the measurements reports to the UTRAN, the UTRAN correlates the measurements with the physical attributes of the E-UTRAN channels. This ensures that the call transfer performed exactly to correct the destination E-UTRAN channel that you want Bitrate and delay requirements supported.
